持水能 meaning in English
ecificretention
specific retention
Examples
- The soil water - retaining capacity at low and moderate intensity burnt site returned to the level before burning faster than at high intensity burnt site
低、中强度火烧迹地土壤持水能力的恢复较高强度火烧迹地快。 - 2 . by detection and analysis on litter accumulation , water ? olding capacity of the litter and interception of main types of forests , its waterolding capacity , intercepting role , water storage and soil reduction of litter were studied
2通过对祁连山水源涵养林凋落物累计量、枯枝落叶持水能力以及截留作用测定分析，研究了枯落物叶层的持水、截留作用和蓄水保土效益。 - With the development of human society , because of the lack of sustainable utilization consciousness , and the eager for quick success and instant benefit , the black earth suffered excessive cultivation and management , causing the reduction of its recycled ability , decrease in organic content , porosity ratio , fertility dropped and the properties of water retaining and water retention , which make the black soil harden and degenerate seriously
但是随着人类社会的发展，在缺乏保护和可持续利用意识、急功近利思想影响下，黑土遭到过度垦殖和掠夺式经营，人类对其活动范围远远超过了其再生能力，导致有机质含量减少，肥力下降，孔隙比减小，保水持水能力降低，土壤板结，黑土严重退化。 - At the same time , the quality of different - state water was studied . the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth , specifically 0 . 74 > 0 . 94 andl . 34g / cm3 , the saturated , canaliculus and field moisture contents decrease gradually in layer a , b and c , accordingly the soil total foveola decreases gradually , and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space , which are respectively 0 . 92 and 0 . 99g / cm3 , and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
结果表明：冷杉原始森林土壤容重随土层深度的增加而增大，分别为0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，饱和持水量、毛管持水量、田间持水量a层、 b层、 c层逐渐减小，十壤总孔隙度也逐渐减小，土壤的持水能力随深度的增加逐渐减弱；林外空地a层、 b层十壤容重相差不人，分别为0 . 92和0 . 99g cm ~ 3 ，其它规律与林内人体相同：皆伐迹地的低洼地段容易发生逆行演替，形成高原沼泽地。
